so every ounce in awile when I get on it it will try to boost but kinda boogs and doesn't boost other times it boosts fine any ideas?

 

Worn out bypass solenoid?

 

Check the butterfly valve on the supercharger, you have to take of the sc to get to it

 

how do you test it to c if its working?

 

try posting this in problems and service

google the boost bypass mod

 

I just did but no replies

 

google the bypass mod and try it

 

Didnt work for me. All plugging that hole did was give me a fucked idle to the point where it would stall out.

 

Vac leak

 

If you haven't figured it out yet, the search function on this site is screwy. bad.

your best bet for any css.net searches is to actually go to google, type your search, and add cobaltss or cobaltss.net to the end of the google search.

 

site:cobaltss.net will search just the forum

 

yea im not gna try that lol that's what I read

 

Must be. Im getting gm to pressurize the system this week cause i dont have garage space or any of the **** to do it. i got the car to idle fine tonight after 10 minutes of ******* with it. idles good when shes warm

 

then you did it wrong or you got a different problem

there are 2 things that control it 1 is the boost bypass solenoid and the boost bypass actuator by correctly doing the boost bypass mod you take the solenoid out of the circuit and then that leaves the boost bypass actuator if you disable the solenoid by removing the vacuum source and you still have a low pressure problem then you either have a bad actuator or cracked vacuum lines or a stuck open butterfly on the blower

 

told him to take the blower off and check, but i think this was looked over.

 

yea im deff gna check that out and make sure no vac leak

 

o ok I get what u are saying I googled it and it was coming up with everyone that said there car ran worse after
